Bottom Paint

What do I need to do to keep the bottom paint on the boat,it keeps coming off in the same spots.

Thanks for the help

Lay it on thicker. Don't put the boat in the water, it will last longer.

Bottom paint is supposed to come off. The idea is that the growth on the hull  is not actually slowed down ,but minuscule layers of the bottom paint come off together with the growth that gets onto the bottom. The end result is a clean bottom ,but the paint has to be replenished every so often. If your boat is kept on a trailer year round the process will be much slower and you will not have to repaint as often.

Chances are your area of application has oil or something contaminating the gelcoat, try sanding with 80 grit and re apply.

OK thanks for all your help.I think sanding where the paint comes for is worth a try,if doesn't work my be some primer might. Thanks

You would need to sand then clean with acetone but most bottom paints are designed for boats that are left in the water all year so there is really no point to bottom paint due to there is a type of living enzyme in it to fight algae and that stops working when the boat is left out of the water .

Note you can get bottom paint for towed boats just be shur to buy the correct one.

When I got the boat the previous owner left it the water I leave it in the water for a mouth I don't know what kind of paint is on there. Can I put paint for towed boats on top of whats there?

Thanks
